1 Claim. (01. 22992.1)

back 'wall 2 of the .envelopeand as seen in Fig- Our present invention relates to improvements in envelopes or mailing packets, adapted especially for use as unsealed or second-class mail matter. In carrying out our invention we employ a single blank of stiff paper, cardboard, or other suitable material, which is fashioned as an envelope or container, together with a strip that is made into a plurality of foldable and unfoldable leaves adapted to be inserted into and withdrawn from the envelope or pocket. These parts are so associated and related that the pull tab, although inconspicuous, is located at or near the bottom edge of the front face or wall of the envelope or container, thereby permitting the sender and the receiver of the packet to observe the address on the envelope at the same time the foldable strip is being inserted as well as when the foldable strip is being withdrawn. Thus, in mailing the packet, the sender is permitted to v have a final inspection of the address, and when the packet is received, the receiver while inspecting the address, has his attention invited to the pull tab, thereby disclosing to the recipient the nature of the packet. An additional advantage in the association and relation of parts of the mailing packet resides in the fact that the envelope may conveniently be held in the left hand while the inscription on the face of the envelope is being read, and the right hand is natu- 30 rally free for use in pulling the tab to withdraw the folded strip from the envelope.

Our invention consists essentially in a mailing packet comprising an envelope and a strip fashioned from a single blank in which the strip is foldable and unfoldable for insertion into and withdrawal from the envelope, in the specific construction of the envelope, and in the manner of locking the folded strip within the envelope, all as will be hereinafter more fully set forth and claimed.

In the accompanying drawing we have illustrated one complete example of the physical embodiment of our invention, wherein the parts are combined and arranged according to one mode we have thus far devised for the practical application of the principles of our invention.

Figure 1 is a face view of the mailing packet ready for the address and mailing.

Figure 2 is a view showing the unfolded blank, partly broken away for convenience of illustration.

Figure 3 is a perspective view of the blank indicating its folds.

The single strip from which the mailing packet is fashioned includes the front wall 1 and the ure 1 the outer face of the front wall 1 is used for the address and postage stamp in usual manner. In addition to the envelope portion of the packet the blank is fashioned with foldable leaves 2 5, and 6, and the blank or strip is bent or folded'on the transverse, dotted lines 7 to guide, and facilitate the folding and unfolding of the leaves.

The end of the front wall 1 of the envelope '65 or container is fashioned with spaced extensions 8 and 9, which, between them, form a recess 10 in the outer edge of the wall, and when the gummed edges 11, 11, at opposite sides of the front wall are pressed down on the complementary edges of the back wall 2, the outer free ends of these extensions are flush with the shoulders 12 12 of the wall 2. Thus, the foldable leaves 3, 4, 5, and 6 are narrower than the portions 1 and 2 forming the envelope, and the recess 10 is of sumcient width to form a slit or opening 13 at or near the bottom edge of the envelope to permit insertion of or withdrawal of the folded leaves from the pocket.

The gummed strips 11 at the edges of the front 3 wall 1 are of course on the side of the wall that becomes the inner side of the wall, and these gummed stripsare approximately the width of the extensions 8 and 9, in order that when the wall 1 is folded over flat on the wall 2, the two 1 walls may be made to adhere and form the envelope.

The free edge of the outermost leaf 6 is fashioned with a thumb piece or pull tab 14, which is marked Pull, and as indicated in Figure 1, when 5 the folded leaves are encased within the envelope, this tab projects across the recess 10 or opening 13 in full View, in order that it may be grasped between the thumb and finger for withdrawing the folded leaves.

One or more of the foldable leaves may be provided with corner, diagonal, slits as 15, for the reception of the corners of a card as 16, and in addition, a flap 1? may be punched or cut out of the leaf to be used as a retainer for the card,- and also used for advertising purposes. Thus the card 16 may be used as an added insert, or advertising feature.

The foldable leaves are provided with any suitable advertising matter or message, in printed, form or in the form of illustrations of suitable character, and the back face of the envelope may also be used for suitable advertising purposes,

bears the inscription and postage stamp.

The gummed strips 11 may be made to adhere and form the envelope or pocket before the foldable leaves are inserted therein; or these leaves may be folded together and then folded on the back wall 2, after which the front wall of the packet is foldedover and its gummed edges sealed to enclose the folded strip.

In either event, the leaves may with facility and convenience be folded and encased within the envelope in such manner as to completely enclose the printed matter or advertising, as for instance a circular letter; the folded leaves due to their frictional contact with one another and with the inner faces of the Walls of the envelope are retained against displacement; and the recessed front wall at its lower edge, protects the end leaf 3 against tearing and holds the leaf outer end leaf 6 against displacement. The narrowed strip provides for a neat and snug fit of the folded leaves within the envelope, and the exposed portion of the leaf 3 in Figure 1 fills the recessed opening 1013 so that the exposed part of the leaf is flush with the faces of the two extensions 8 and 9, thereby insuring a smooth surface for the face of the envelope, and avoiding the possibility of the packet becoming entangled with other mail matter in transit.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is:- V

A mailing packet comprising folded front and back walls sealed at their side edges to form an envelope, spaced extensions at the edges of the front wall forming a recessed opening at the bottom of the envelope, a strip of a reduced width integral with the back wall of the envelope and comprising a plurality of foldable leaves adapted for insertion in the envelope, and a pull-tab at the free edge of the outermost leaf located in the recessed opening for ready access.
